Product overview: Fluke 1770 Series Three-Phase Power Quality Analyzers

Automatic measurements. More flexibility. Better power quality troubleshooting.

Fluke 1770 Series Three-Phase Power Quality Analyzers eliminate the complexities of power quality logging, troubleshooting, and analysis. Engineered to be the faster, easier way to perform power quality studies, the 1770 Series offers automatic measurements, a straightforward user interface and setup, best-in-class specifications, and a simplified reporting platform. The instrument can also be powered directly from the measurement circuit, eliminating the need to find a power outlet or use a lengthy extension cord

With the 1770 Series you’ll never miss a critical power quality event—from fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, as well as the voltage, current, and power measurements that enable you to characterize your electrical system.

Automatic measurement capture

Whether you’re performing a quick system check or a detailed power quality study, consistent data is key. The Fluke 1770 Series offers a unique automatic measurement capture system that helps ensure you’re collecting the right data every time, while still giving you the flexibility to select and adjust specific parameters as needed. More than 500 power quality parameters are captured by default and the guided setup makes it easy to select the right parameters for the system you’re working on. Logged data is instantly viewable, downloadable, and shareable with Fluke Energy Analyze Plus software so you never need to wait to finish a session before reviewing results or analyzing data.

Fluke 1770 Series Three-Phase Power Quality Analyzers Overview
Power Quality Logger

Ultimate measurement confidence

The Fluke 1770 Series are 2-in-1 devices that combine the troubleshooting functionality of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyzer—in a single, easy-to-use, handheld device.

The ‘PQ Meter’ function gives you immediate access to live onscreen data in the field so you can quickly identify potential problems while troubleshooting. The detailed ‘PQ Logging and Analysis’ function eliminates the complexity of performing power quality studies by guiding you through the setup process ensuring you’re capturing the right data every time. Couple these measurement modes with a unique measurement connection autocorrect function and you can be confident that you never need to worry about going back for a second measurement—even if you were unsure about what to look for when you started.

Powerful analysis software with easy-to-create reports

Fluke 1770 Series Power Quality Analyzers come standard with the powerful Fluke Energy Analyze Plus software, designed to eliminate the hassles found with other multi-purpose application software. Energy Analyze Plus helps you evaluate power quality data right out of the box and without extensive training.

Energy Analyze Plus makes downloading, analyzing, tracking, and reporting power quality and energy data easier than ever. Quickly compare results to historical values, benchmark against industry norms, compare measured data to local conditions, and create a more complete picture of what’s occurring across your facility, even as the data is still being collected. Energy Analyze Plus offers unified support for the Fluke 1730, 1740, and 1770 Series of Energy Loggers and Power Quality Analyzers.

  • “In-workshop” and “in-the-field” setup and download through PC application software
  • Simple data downloads using USB memory stick, WiFi, LTE, wired Ethernet, or USB cable
  • Analyze every measured detail of energy consumption and power quality state-of-health with automated reporting
  • One-touch reporting creates standardized reports conforming to standards like EN 50160, IEEE 519, GOST 33073 IEC 61000-2-2, or export data in PQDIF or NeQual compatible format or CSV for use with third-party software
  • Advanced analysis allows the user to choose any available logged parameter and create a highly customized view of measurements for advanced data correlation
Power Quality
Power Quality Logger Transient

High-speed voltage transient capture

Transients negatively impact otherwise healthy systems every day and their potential to damage your equipment can’t be underestimated. Whether your system is experiencing impulsive or oscillatory transients, the results can be devastating and cause problems ranging from insulation failures to total equipment failures. The Fluke 1775 and Fluke 1777 incorporate advanced transient capture technology to help you clearly identify high-speed voltage transients, so you have the data you need to stop them in their tracks. The Fluke 1775 Power Quality Analyzer has 1MHz sampling capability to capture fast transients, while the Fluke 1777 Power Quality Analyzer has 20MHz sampling capability to capture the fastest transients in high detail.

From traditional industrial systems to renewable energy systems to electric vehicles, we’ve got you covered

The Fluke 1770 Series was designed to be safe and easy to use in any measurement environ¬ment. The 1770 Series allows you to capture a full range of power quality variables as well as high-speed waveforms, high-speed transients, and higher frequency harmonics, all of which are instantly viewable on the large, high-resolution screen. With a best-in-class CAT IV 600 V / CAT III 1000 V overvoltage rating, these analyzers can be used at the service entrance or downstream, measuring AC and DC inputs, and harmonics measuring up to 30 kHz. With the 1770 Series you can be confident that you’ll capture the data you need to make better maintenance decisions no matter the task.

Compliant to international standards

The Fluke 1770 Series offers the best-in-class accuracy you’ve come to expect from a Fluke Power Quality Analyzer in a future IEC 61000-4-30 Class A edition 3 compliant package. On top of that, the 1770 Series has been engineered to meet the future requirements of Class A edition, for conformance to EN 50160 and IEEE 519, so you’ll be prepared to tackle tomorrow’s measurement requirements, today.

Fluke 1770 Series Three-Phase Power Quality Analyzers

Work where, when, and how you want

No two days in the field are the same. You need a power quality analyzer that can go where you go and do what you need it to when you get there. With a full range of accessories and built-in features the Fluke 1770 Series makes it easier to get your job done. The slim ergonomic design and integrated hand strap make it easy to hold and the included hanging kit makes it easy to secure your analyzer inside a cabinet. The integrated internal power supply allows the unit to be powered directly from the measured circuit, while a 90-minute battery helps ensure you can still access and review data even when you aren’t connected to a live system.

Quickly and easily transfer data to your PC using the USB C, USB A, Ethernet, Wi-Fi, cellular network support options, depending on your requirements. With an internal GPS module and an optional double insulated antenna extension cable, for amplifying GPS signals indoors, you can easily time sync your data for more accurate troubleshooting and analysis.

Calculate current harmonics limits

When downloading data from the Fluke 1770 Series Power Quality Analyzers the included Energy Analyze Plus software package can compare measured voltage and current harmonic statistical data to different standards, like EN 50160 or IEEE 519, to determine if they exceed compliance limits. This powerful predictive maintenance feature enables current harmonics to be observed before distortion appears in the voltage allowing you to prevent unexpected failures or non-compliance situations and increase system uptime. With the proliferation of inverter-based loads and power generation, keeping current harmonics in check is becoming increasingly critical to ensure reliable power quality and avoid system downtime.
